Supplementary charts show the percentages of rural population, urban population in places with populations of 5000 or more and urban populations that are...

This map shows the population distribution in 1996 relative to the distribution of the forests. Even if forests are very important for Canadians from a cultural, spiritual and economical point of view, few people live in the forested areas. About 80% of the population live mainly in the urban...
